    Many studies on research productivity and performance suggest that men consistently outperform women. However, women and men are spread unevenly throughout the academy both horizontally (e.g., by scientific field) and vertically (e.g., by academic position), suggesting that aggregate numbers (comparing all men with all women) may reflect the different publication practices in different corners of the academy rather than gender per se. We use Norwegian bibliometric data to examine how the “what” (which publication practices are measured) and the “who” (how the population sample is disaggregated) matter in assessing apparent gender differences among academics in Norway. We investigate four clusters of indicators related to publication volume, publication type, authorship, and impact or quality (12 indicators in total) and explore how disaggregating the population by scientific field, institutional affiliation, academic position, and age changes the gender gaps that appear at the aggregate level. For most (but not all) indicators, we find that gender differences disappear or are strongly reduced after disaggregation. This suggests a composition effect, whereby apparent gender differences in productivity can to a considerable degree be ascribed to the composition of the group examined and the different publication practices common to specific groups. We argue that aggregate figures can exaggerate some gender disparities while obscuring others. Our study illustrates the situated nature of research productivity and the importance of comparing men and women within similar academic positions or scientific fields—of comparing apples with apples—when using bibliometric indicators to identify gender disparities in research productivity. © 2022, The Author(s).

    What's in a number? How (and why) measuring research productivity in different ways changes the gender gap Open PDF

    A persistent finding in studies of research productivity is the ‘gender gap’ where men seem to publish more academic research than women. However, this gap varies widely from study to study, and little has been done to explore how these claims might be sensitive to what is being measured and how. Using a dataset of publications statistics spanning five years for a Norwegian social science research institute, this paper looks at how (and why) measuring productivity in different ways provides different pictures of the gender gap. Based on the situated context of the institute, we also disaggregate the data by staff category, methodological orientation, and language background, and consider the impact of leaves of absence. We find widely varying measures of the gender gap depending on how we measure and disaggregate, and argue that different bibliometric indicators capture different aspects of research performance, including diversity of output and collaboration, which reflect different publication practices that are both gendered and situated. We suggest that looking at academic writing as a situated - and gendered - social practice offers a potential for deriving more theoretically consistent explanations for both the seeming persistence of the gender gap and the wide contextual variations. © 2018 Elsevier Ltd

    Scientific Performance Assessments Through a Gender Lens: a Case Study on Evaluation and Selection Practices in Academia
    (2018)
    Nielsen, Matthias Wullum
    The focus on excellence and quality assurance in the academy has spawned a significant increase in the use of bibliometric measures in performance assessments of individual researchers. This article investigates the organizational consequences of this development through a gender lens. Based on a qualitative case study of evaluation and selection practices at a Danish university, a number of potential gender biases related to the use of bibliometric performance measures are identified. By taking as default the research preferences, approaches and career paths of a succesful group of predominantly male scholars, evaluators using bibliometrics risk disadvantaging candidates diverging from the norm with implications for gender stratification. Despite these potential biases, bibliometric measures come to function as technologies supporting a managerial narrative of the gender-blind organization. They adhere to the prevailing ethos of the academic meritocracy by standardizing the criteria for organizational advancement and ensuring transparency and accountability in the selection process. While bibliometric tools in this sense may lead to the recruitment of scientists with a strong CV and track record, they may at the same time prevent many talented researchers diverging from the norm from being recognized and succeed as academics.

    In the previous literature, no clear conclusions have been reached about the effect of gender differences on research performance (RP) in science, as measured by publication productivity, number of citations, and academic awards. Meanwhile, a gap also exists in the research regarding gender differences in international academic collaboration. To complement the existing literature, this study investigated the achievements of scientists engaged in international academic collaboration, which places heavy demands on language and communication skills and in which female scientists appear to have more advantages than male scientists. We investigated the effect of international collaboration carried out by chemists from China's Project 985 universities and the Chinese Academy of Sciences and compared the extent to which the international collaboration improved female and male scientists' academic performance. The results indicated that, compared to male scientists, female scientists performed better and significantly improved their academic performance through international collaboration. This conclusion was valid for different periods throughout chemists' academic careers. The policy implications are discussed at the end of this study. © 2020 Elsevier Ltd.

    Gender and research publishing analyzed through the lenses of discipline, institution types, impact and international collaboration: a case study from India Open PDF

    Higher participation of women in higher education and research is a very important development goal in many countries across the world, with several countries creating special initiatives and schemes to increase participation of women in higher education and research. This article looks at a case study from India and aims to characterize the participation of women in research, by analysing the parameters of institution-type, discipline, citation impact and international collaboration. Research publication data from 50 most productive Indian institutions, along with data for 5 major institution systems, for a period of 10 years (2008–2017), as indexed in Web of Science, is obtained as sample data and analysed. Results obtained show that participation of women is found to vary in different disciplines, with biology (37%), agriculture science (32%), social science (31%) and medical science (32%) having relatively higher number of female 1st authored papers as compared to engineering (20%), information science (21%) and mathematics (22%). It is also observed that institutions specializing in medical sciences and social science have relatively better participation of women. In terms of location of institution in a big metropolitan city or an urban area, it was found that there do not exist any significant differentiation in levels of participation of women in research between institutions located in bigger cities or smaller towns. Further, analysis of citation and collaboration patterns show that though male authored papers have an edge in citation impact, women researchers get more internationally collaborated papers. © 2020, Akadémiai Kiadó, Budapest, Hungary.
